Intent of License</a></h2>
<p>(This section is informal and not legally binding.)</p>
<p><br/>
 This library is free code-- you can use it without charge and it is minimally legally encumbered. Unlike some other free libraries, we <b>do not</b> require you to release your source code or make your own program open source.</p>
<p>I intend the license (below) to protect me and the other contributors from liability and allow you to use the source however you want. You can make your own closed or open-source programs, sell them, give them away, whatever.</p>
<p>The license for <a class="el" href="namespace_g3_d.html">G3D</a> itself and the libaries included in the <a class="el" href="namespace_g3_d.html">G3D</a> distribution create certain documentation obligations for you. For convenience, <a class="el" href="namespace_g3_d.html#a2d6bccd0c2fa5b44882b7d0c732e2712" title="G3D, SDL, and IJG libraries require license documentation to be distributed with...">G3D::license</a> is a function that returns the license string you must put in your documentation. <a class="el" href="class_g3_d_1_1_g_app.html" title="For each frame, the GApp has several tasks that can be implemented by overriding...">G3D::GApp</a> will automatically write a file (g3d-license.txt) to disk with the contents of this license unless you tell it not to, thus automatically satisfying your documentation requirement after the first time you run a <a class="el" href="namespace_g3_d.html">G3D</a> program.</p>
<p>Most of the data resources have either entered the public domain and have been in several published papers or are data that I have explicitly received permission to distribute with <a class="el" href="namespace_g3_d.html">G3D</a>. The <a class="el" href="namespace_g3_d.html">G3D</a> fonts are actually font images, not TrueType font descriptions and may be freely distributed. As a rule of thumb, you can freely use and distribute anything you find in the data directory but may need permission to use it in a commercial product. Check the various copyright.txt files in the data directories for specific information.</p>
<p>You are required by the BSD license to acknowledge <a class="el" href="namespace_g3_d.html">G3D</a> in your documentation. This can be as minimal as a note buried in the fine print at the end of a manual or a text file accompanying your program. I appreciate it if you acknowledged the library more publicly but you aren't required to.</p>
<p>Likewise, you are encouraged but not required to submit patches to improve the library for the benefit of all. Post bugs, patches, and questions to the g3d-users forum linked at the top of this page. </p>
